Before opening a valve

Use an approved dump station and dedicated wastewater gloves and hose.
Locate the sewer outlet and identify every black and gray valve.
Seat and check both hose connections; keep potable-water gear separate.

Notes, readings, or follow-up needed

Empty and clean

Follow the RV’s valve sequence; for a typical gravity setup, black precedes gray.
Monitor tank discharge and close each valve when its step is complete.
Use a built-in flush only with the exact manual’s valve and backflow instructions.
Rinse where permitted; cap and store contaminated equipment separately.

Notes, readings, or follow-up needed

Before departure

Check outlet cap, valve positions, and service-bay leaks.
Wash hands after removing gloves.
Record a sticking valve, leaking fitting, or gauge reading that needs follow-up.
